“…L 2 (AlMe 2 ) 4 ?2THF?2toluene [L ~bis (2,6-diisopropylanilino)squaraine] was prepared by the reaction of trimethylaluminium with bis(2,6diisopropylanilino)squaraine, which was in turn made by the treatment of 2,6-diisopropylaniline with squaric acid. 98 Finally for Group 13, two dichlorogallium(III) b-diketonato compounds, GaCl 2 (acac) and GaCl 2 (tmhd), have been isolated. The crystal structure of the adduct GaCl 2 (acac)?THF identifies the compound as an ion pair with Ga six-coordinate in the cation [trans-Ga(acac) 2 (THF) 2 ] 1 and four-coordinate in the anion [GaCl 4 ] 2 .…”

This chapter reviews original highlights in the chemistry of the Group 16 elements reported during 2003. The bulk of the review focuses on the chemistry/interaction of the chalcogens with other p-block elements. Due to the vast abundance and diversity of research into chalcogen chemistry, the report has been limited to materials with discrete molecular structure, either as novel products or reagents, or obtained by new synthetic strategies. The most important advances in 2003 include the isolation of hitherto unknown functionalities or bonding modes,

The Al/P-based frustrated Lewis pair (FLP) Mes P-C(AltBu) =C(H)Ph (1; Mes=mesityl) reacted as an efficient two-electron reductant with benzil to afford a cis-enediolate that was coordinated to the FLP through P-O and Al-O bonds and the formation of a seven-membered heterocycle (2). The phosphorus atom is oxidised from +III to +V. Similar heterocycles (3 a to 3 f) were formed if 1 was treated with various enones (acrolein, acrylate, acrylamide). The resulting enolates are bound to the FLP through P-C and Al-O bonds. Cyclopropenone gave an adduct (4) with the C=O bond coordinated by P and Al. Ynones gave a fascinating variety of different structures. 1,3-Diphenylprop-2-yn-1-one afforded a remarkable allene-type moiety with two cumulated C=C bonds (5); 3-hexyn-2-one yielded a ligand with two conjugated C=C bonds by C-H bond activation at the carbonyl methyl group (7); and 4-(trimethylsilyl)-3-butyn-2-one reacted by C-H bond cleavage, formation of an enolate group with a terminal C=C bond, and shift of the proton to the P atom (8). The C≡C bond was not affected. Allene compound 5 rearranged at elevated temperature and in daylight through the formation of a tricyclic compound by C-H bond activation and C-C bond formation. DFT calculations on this unusual rearrangement suggest insertion of the central allene C atom into the C-H bond of a methyl group and the intermediate formation of a C ring.
